To demonstrate the restorative process of recreation, the function of a pencil will be used. A wooden pencil, when sharpened, fully functions to aid in the writing of words on a piece of paper. But should one write for an extended period of time, wearing the lead down until it no longer extends from the end of the pencil, the pencil can no longer function as it did in its original state. However, the worn-down pencil can be easily restored to its original condition by simply sharpening the pencil. In this scenario, the pencil was not re-created; it was simply restored. Now, if one were to take a hammer and smash the pencil, both wood and lead, into splinters and dust, the pencil would need to be re-created anew before it could function in its original state as a writing device. As with the pencil demonstration, we are seldom involved in recreation with the process of creating as new something that has been destroyed and lost, but rather, we are involved in the recovery and restoration of something that is worn out and fatigued so that it is once again in a wholesome functioning condition.
Even with Kelly’s restorative definition of recreation and the pencil demonstration, we are still without a psychological and physiological foundation for how the fatigue, recovery, and restoration processes occur. Fortunately, attention restoration theory (ART) provides an explanation for both the fatigue and recovery/restoration processes (Kaplan 1995).
The fatiguing process concerns two types of mental attention states utilized by humans while processing information and functioning in most environmental settings. The first type of attention is involuntary, which requires little effort in terms of remaining focused on the environmental information to be processed. It is employed when the stimuli, in terms of both content and process, are interesting, involving, and automatically hold our mental alertness and focus. As a result, involuntary attention is a pleasurable mode of environmental information processing and functioning, and comes at no cost to humans.
Unfortunately, not all social and work environmental stimuli are interesting and involving in terms of information processing and functioning. In fact, the majority of our everyday existence may find us in environmental settings where the stimuli we must deal with are not the most interesting and involving, yet must be processed and acted upon. In these situations, humans must call upon directed attention. This involves a forced and burdensome form of focused attention that requires great effort to remain with the information and task functioning at hand. The stimuli that must be dealt with may be mentally demanding and of little interest in terms of desired mental involvement. While people seem to be quite efficient at using directed attention, there is a mental fatiguing cost and it can only be employed efficiently for a limited period. As the mind (and perhaps the body) tires from the forced attention required, it wanders to more appealing stimuli, thereby decreasing the efficiency of directed attention. When this occurs, a period is necessary to allow recovery from mental fatigue and restoration of the ability to use directed attention once again as necessary.
The restorative process therefore involves recovery from the cost and pain associated with directed attention and mental fatigue. Kaplan (1995) theorizes that the restorative process involves the recovery of a worn-out inhibitor control mechanism that is employed by humans during directed attention to ward off or inhibit more appealing stimuli from dominating our attention. The means by which the inhibitor control mechanism is restored is to not use it; to use no-cost involuntary attention instead of the costly directed attention. How is this done? By seeking environmental settings where the dominant form of information processing and functioning is involuntary attention. Such environments and experiences are restorative. Restorative environments and experiences provide for states of involuntary attention, where the inhibitor control can recover and we restore the ability once again to use directed attention when needed (Kaplan 1995). The availability of restorative environments, for which most outdoor and wildland recreation areas qualify, are essential for the recreation restorative experience (Hammitt 2005).
